Description

Technical Field

[0001] This utility model belongs to the field of bending machine technology, and in particular relates to a sheet metal forming device that uses a bending machine mold to modify the sheet metal forming process. Background Technology

[0002] Equipment idle costs refer to a series of expenses incurred when equipment is idle, such as equipment depreciation, site occupancy fees, and maintenance costs. These costs increase the operational burden on enterprises and reduce their profit margins. For example, in manufacturing enterprises, if a large number of equipment are idle, not only can the purchase cost of the equipment not be effectively amortized, but continuous maintenance costs are also required, which undoubtedly increases the enterprise's production costs. Specifically, in the sheet metal processing industry, the production of a single product often involves two processes: stamping and bending. During the stamping process, the bending machine is idle, thus generating equipment idle costs.

[0003] Chinese patent document CN211489329U discloses a stamping-type bending machine mold, belonging to the field of bending machine technology. The stamping-type bending machine mold includes a base, an operating table fixedly connected to the top of the base, a bracket fixedly connected to the top of the operating table, a support arm fixedly connected to one side of the bracket, a hydraulic punch fixedly connected to one end of the support arm, a load-bearing plate fixedly connected to the bottom of the hydraulic punch, a spring cylinder inserted into the top of the load-bearing plate, and a limit rod inserted into the bottom of the spring cylinder. By setting up the spring cylinder, spring, limit rod, and pressure plate, when the hydraulic punch descends, the pressure plate preferentially contacts the sheet metal to be processed. During the continuous descent of the hydraulic punch, the pressure plate compresses the spring inside the spring cylinder through the limit rod. The reaction force of the compressed spring is fed back to the pressure plate, and the pressure plate completes the fixing of the sheet metal, thus achieving the effect of simple and convenient sheet metal fixing by the mold.

[0004] The aforementioned patented solution achieves the function of a bending machine by installing a die on a stamping press for bending, thus reducing equipment downtime costs. However, both stamping and bending operations require customized dies. The customization cost of stamping or bending dies is inherently high, and the dies have low compatibility. Clearly, the usage cost of the aforementioned patented solution remains relatively high, and to some extent, it cannot meet actual usage needs. Utility Model Content

[0005] To overcome the problem that equipment idle costs increase production costs in existing technologies, while installing bending dies on stamping presses reduces idle costs, the high customization cost and low commonality of these dies still result in high production costs. One objective of this invention is to provide a sheet metal forming device that uses a modified bending machine die. By installing a stamping die on the bending machine, the machine still uses universal dies for bending operations, reducing die costs. Furthermore, when using the stamping die, a calibration plate is installed on the bending machine's worktable for positioning, facilitating material placement and location, thus enabling mass production and manual operation.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a sheet metal forming device modified from a bending machine mold, comprising two stamping parts respectively disposed on a bending machine worktable and a slide table; each stamping part includes a mounting base disposed on the bending machine, a sliding plate longitudinally slidably connected to the mounting base, and a spring disposed between the sliding plate and the mounting base; the two sliding plates face each other, and the spring force is used to make the two sliding plates slide towards each other; wherein, at least one of the mounting bases is provided with a punch, the punch being located between the mounting base and the adjacent sliding plate; the punch can optionally extend from the sliding plate; a calibration plate is slidably connected behind the worktable between the two stamping parts.

[0007] Furthermore, a T-slot is provided on the worktable; a mounting plate is provided on the T-slot; two optical axes are provided on the mounting plate and are slidably connected to the calibration plate; a lead screw is provided on the mounting plate between the two optical axes; and an adjusting disc is rotatably connected to the lead screw and threadedly connected to the calibration plate.

[0008] Specifically, a scale is provided on the optical axis; and an indicator mark is provided on the calibration plate that is directly opposite the scale.

[0009] The slide of a bending machine is often quite long, allowing multiple pairs of stamping sections to be arranged simultaneously. Through the positioning function of the calibration plate, multiple workpieces with different dimensional requirements can be processed simultaneously, or both sides of the same workpiece can be processed simultaneously. Although bending machines also have baffles for dimensional positioning, there is only one, and each forming device can only process the same workpiece, resulting in poor flexibility. By rotating the adjusting plate to adjust the position of the calibration plate and placing the workpiece until it abuts against the calibration plate, the workpiece positioning between the two stamping sections is completed.

[0010] Furthermore, a positioning plate is provided on the side of the mounting base facing the sliding plate; two main guide columns are provided on the positioning plate on the worktable; two main through holes are provided on the positioning plate on the sliding plate; the two main guide columns are respectively opposite to the two main through holes; and a tapered head is provided at the end of the main guide column.

[0011] The main guide post passes through the main through hole to position or correct the relative position of the two stamping parts, thereby improving the machining positioning accuracy of the workpiece.

[0012] Specifically, the positioning plate has an embedded groove at one end facing the mounting base; the punch has an end cap at one end facing the mounting base; and the end cap is located within the embedded groove.

[0013] Specifically, the sliding plate has two sliding tubes that are slidably connected to the positioning plate at one end facing the mounting base; the mounting base has two sliding cavities that are respectively opposite to the two sliding tubes at one end facing the positioning plate.

[0014] Specifically, the positioning plate has a through hole; the sliding plate has a pressure groove at one end facing the mounting base; the spring is located in the through hole, and the two ends of the spring abut against the bottom of the pressure groove and the end of the mounting base facing the positioning plate, respectively.

[0015] Furthermore, the sliding plate on the worktable is provided with two secondary guide posts; the sliding plate on the worktable is provided with two secondary through holes; the two secondary guide posts are respectively opposite to the two secondary through holes; and the ends of the secondary guide posts are provided with tapered heads.

[0016] The secondary guide post is inserted into the secondary through hole to position or correct the relative position of the two sliding plates, thereby improving the machining positioning accuracy of the workpiece.

[0017] Furthermore, the sliding plate is provided with a guide hole that is slidably connected to the punch; the sliding plate is provided with a clearance hole, and the clearance hole on one sliding plate is directly opposite the guide hole on the other sliding plate; the cross-sectional area of ​​the clearance hole is larger than the cross-sectional area of ​​the guide hole directly opposite it.

[0018] Furthermore, the mounting base on the slide is provided with an abutment platform at its rear end, which abuts against the lower end of the slide; the mounting base on the slide is provided with a slot at its front end; and a clamp for fixing the slot is detachably connected to the slide.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model enables sheet metal parts to be stamped or straightened by setting a stamping die on the bending machine. At the same time, the bending machine can still use a general bending die for bending, which not only reduces the idle cost of the equipment and increases the utilization rate of the equipment, but also lowers the die cost and production cost.

[0021] 2. In the stamping process of this utility model, the two sliding plates first clamp the workpiece to prevent the position from shifting, and then the stamping is carried out, which helps to improve the stamping pressure and reduce the wear of the punch. After the stamping is completed, the spring force causes the sliding plate to slide relative to the punch, and the sliding plate pushes the workpiece out of the punch to prevent the workpiece from getting stuck on the punch and facilitates the picking and putting of the workpiece.

[0022] 3. This utility model can simultaneously set multiple pairs of stamping parts on a bending machine, and through the setting of a calibration plate, it is convenient to position the placed workpiece. It can process multiple products with different size / position requirements at the same time, or process the front and back sides of the same product, which improves processing efficiency and facilitates mass production.

[0023] 4. This utility model has a main guide post and a main through hole, a secondary guide post and a secondary through hole respectively set on the positioning plate and the sliding plate, which improves the relative position accuracy of the two stamping parts, helps to improve the processing accuracy of the product, and can also reduce the wear of the punch.
